FLOAT VALVE.

Application filed March 24,' 1919. Serial 1 l 0 ..,284,586. i

. To all whom it may concern Be it known that I, EDMUND B. LALSALLE',

a citizen of the United States, residing at" The object of my invention is the produc .tlOIl of a device of this. character which will be of durable and economical construction,

taken apart to renew or repair a disabled partof the valve, one which will positively prevent overflowing ofv the tank and one which will. be highly efiicient in operation.

Other objects will appear hereinafter.

. Withthese objects'in view, the invention C0I1S1StS 1Il the. combinations and arrange-' mentsof parts hereinafter described and claimed. I

The invention willbe best-understood by reference to the accompanying drawings forming a part of this specification, and in which.-

Fig. 1 isa partially diagrammatic view of awater tank andassociated piping and. elements, in connection with which is arranged a float valve embodying ,the'invention;

Fig. 2 is an axial section through the floa i valve' detached;

/ Fig. ,3- a-section taken on subs tantially line 3-3 of Fig.2; and v s I Fig. 4 a section taken on substantially lineof. Fig. 2.

. The preferred form of construction as 4 illustrated in the drawings, is shown applied to a tank or reservoir 5 with the bottom of which communicates apipe 6 adapted to serve the double function of an inlet; pipe and a discharge pipe. Frov ded, for

cooperation with the. pipe .6, 1s a pump 7 of any rdinary or preferred design, through the medium of which water may be pumped through said pipe into the tank 5. v

1 Ad a cent the lower end f pipe 6 1s a suitable relief valve8 adapted toyield under; a predetermined pressure to permit'of drain from pipe 6.

Also communicating may be drawn from the pipe 6.

Arranged in theitank 5 to-control inlet to and outlet fromthesame is a float valve) which is, arranged in communication withv prisesaabody or housing having. a lower 'part'10' provi ded with a flanged base-'11 with/which, cooperates a companion flange 11 wherebysaid member 10 may be securely part '10'is arranged an upper housing .part

12in the form of-a cap, the arrangement such that a'ohamber 13 is formed" bein within the parts 10' and :12, the lower end upperendofpipe 6. I,

Provided at' the lower edge ofthe-hous:

ing part 12 is ,I an annular" flange 14whichi is adapted to register with an annularfiange coivrrm, OFYBATAVIA, ILLINOIS, Aconron'a'rron or ILL'I-H fastened in position. Above the'housing h' h 't 'thth' one which may be readily and expedltiously O W lab 6 amber communiga W1 e 15 on the upper edge of part 10 and'be se-i cured thereto by bolts orother suitab leQ-fastening devices 16. Betweenthe flanges 14 and 15 is provided. a suitable leather packing against anyleakage through frFo rmed in the housing part 10 adjacent the upper edge thereof is an annularinlet port 18, the same being traversed jatiinter-* vals webbing which connects th'e'body of 4 member 10 with the flangedportion 15thereof as. clearly seen in Figures 2" and 4. v I I Formed in the'topof, housing part12 is an annular outlet port 19 which is also trav+ ersed at intervals by webbing which'con;

aratedby said'outlet port. v y Passage through the inlet port 18 'islcon- .ne'cts the portions of said housing part trolled by a tubular valve or plunger 20 which is slidably mounted within the valve housing, the samebeing carrle'd'at the lower said valve, Said valve passes "loosely end o'fjastem 21 in threaded connection at its lower end with the spider formed Wltlllngio through an opening-22 formed within the flange'15, the lower edge thereof being adapted to engage" with an annular rubber ,valve seat23 arranged in an annularirecess,

24 formed fortheireception thereof in. the

housing part 10'. The seat 23 is held in Q operative position by means of-a clamping ring 25- of angular form in cross sectlon which engages over 'theupperiedgeof said valve'seat, said clamping ring being held in operative relation'with said valve seat, by means of a nut 26 and cooperating bolt 27 which passes through a spider formed, as seen, within-said clamping ring, The lower end of said bolt is anchored in a stationary spiderv 28 formed within the housing part 10, the arrangement being such that the clamping ring 25 maybe forced-into clamping engagement with the valve seat 23 by simply tightening the nut 26. The opening' 22 is of great-er diameter than said clamping ring so-that :in'the event of "renewal of the valve seat, it is'only necessary to detach the upper housing part 12 carrying the va'lve'20 therewith, whereupon the clamping ring'r'nay be released and removed, together i g I the water pressure 'on the anside ''o'tthe'valve with the resilient valve seat 23, through the opening"22. This arrangement is exceptionally convenient, permitting of renewal of -'the'valve seat 23 with thegreatest ease and expedition.

The upper end of the valve stem 21. projects exteriorly, a suitable packingor stuffing box 29 being provided to prevent leakage around said stem. Threaded upon the up-- per end of said valve stem is a bifurcated end piece 30 to which is pi-i' ot'ally connected a lever- 31 fulcrumedat 32 upon the upper end of a link-33pivotally connected at its lower end as at 34-;to the housing 12. Upon the outer end of lever 31 is adj ustably mounted a weigl1t 35 adapted normally, as will be seen; to hold-the valve 20 in elevated 01' open position. Cooperating with said lever {31 is also afloat 36 connected there with by means of a cord, rope or other suitable connecting element 37 The said float serves,of.course, to effect automatic closing of the valve .20 when the level of the water 1n the tank reaches a predetermined point.

. or the control of-the outlet port 19 is prov ded acirCularvalVe 38 which isfreely movable upon the valve stem'21. Upon the upper side'ofqvalve 38 is provided a rubber disk 39 secured'thereto by means'of a metal- .11c clamping ring 4:0 with which cooperates screws 41 having threaded connection with said valve 38. y a

, At the inner end o fthe port 19 are prov dedconcentric; annular valve seats 42, and

$3, said port being positioned between said valve' seats. The arrangement is such that,

' when the valei38 is at its'upper terminalef movement, the rubber disk 39 will engage siniultaneously with the seats 42 and 43 there-' I 'e ife'ctually preventing any leakage through the port 19, The valve seat 43, as

bese en, serves'to guard against leakage wh1ch"m1ght outh'erwise occur around the valvestern 2 1. 'A heh'c'al'comp'ression spring gistprovidedfto hold'the valve 38 in closed position If SLIGh IS'fOHIIG desirable in the operation of the valve as hereinafter more fully set forth. i
